EasyDOS and SpinRite Tech

SpinRite loads from a bootable CDusing EasyDOS and I need to find the Austoexec.bat/config.sys files to load USB drivers for my external drive. SR won't give me a DOS window. Anyone know where to find or put these files so SR will "see" my external USB drive. SR support said check the Internet. I'm running Win7 on a laptop.
